I reported this before as well. Blanking a CDRW on an IDE writerand trying to mount a cdrom on an IDE reader on the slave on thesame IDE channel produces a dual oops. I got an initial responsefrom Alan, and I believe Jens Axboe, and never heard about itagain. I dunno if it was fixed or not. It still oops's though.
